Full description of the problem:
I just got my EVO 4G LTE the other day, as a replacement to my original EVO 4G. However, I noticed when it was plugged into my car's AUX port, it puts out a high-pitch (like a teapot) noise. This noise happens as long as the headphone jack is powered up (something playing). Even if I turn the phone's volume down all the way, the high pitch is still heard. Otherwise, the audio from the phone can also be heard normally.
Things I've tried:
1. Different cables known to work. All act identically.
2. Headphones. They work fine.
3. Another car's AUX port. Worked fine.
4. Jiggling the jack on either end causes the pitch to change momentarily, but does not go away.
5. Slightly unplugging it from the car side (so one of the channels is not connected) makes it go away, leaving me to believe the high pitch noise is only coming from one channel (I believe the right channel, hard to tell).
Things I don't want to do:
1. Get a new car stereo.
2. Use a Bluetooth adapter. I already have the Stereoclip, and it doesn't do phone calls. Anything else sounds awful with music.
Does anyone have any solutions? I think its some sort of strange feedback/grounding issue, but I have no idea how I would fix this.
I don't have a solution, but I am experiencing the same issue with the phone plugged into my car's AUX. As long as music is playing I can't really hear the whine, but between songs it's pretty annoying.
I haven't tried playing around with the different EQ settings. By default it's been going to Beats. I may switch to a different setting or try a different player like Winamp. I'm currently using the HTC media player.

In my experience it has absolutely nothing to do with what app is being used, nor the EQ. It's nothing software as far as I can tell.

if your phone is plugged into the car charger and your audio jack is plugged in to listen to music. what our hearing is a ground loop from the cars alternator. try unplugging the power supply and see if that helps..

The car charger makes no difference. I have tried using nothing but the audio cable in the phone and still had the static.
I was under the impression that a normal ground loop would require a charger, but...
Modplan: are you sure this will fix it if the noise occurs even without the charger plugged in? The noise is high-pitch, not really a hum, so I'm wary as to whether it will help here.
Its not a simple ground loop problem. I wired my power to the phone using a separate ground from the car's common ground and the issue still persisted.
Try cranking the volume up then when you hear the noise, start playing with the touchscreen. When i did this the noise started changing according to the movement of my fingers. I concluded that there is something going on with the grounding of the capacitive display thats causing another grounding issue, but its not an issue with the car, but an issue with the phone.
I didn't want to go through the vicious cycle of returning my phone over and over until i get one that didn't have this fault so i just went with a samsung hs3000 hardwired in to my car.

I wasn't able to replicate this.
I've had the same issue, but it's only when charging. I figured it had something to do with the aluminum body and, as papadunit said, a problem with grounding and your car's alternator and blah blah blah science.

I'm happy to report that this actually did solve the problem, amazingly. Thanks!
Actually had same issues this passed weekend but with my asus transformer. Was using it for navigation tethering from evo with both charging from my 400w inverter. Plugged transformer into aux and had same high pitching noise only when inverter was plugged in. Even tried different audio cables, same chit.

Headset Jack's other issues
I can confirm the same behavior with my EVO 4g LTE. My HTC Touch Pro 2 or Iphone 4s never had any of these issues with my vehicle's AUX jack. I also verified that if I turn the volume on the phone all the way down that the noise is audible on the vehicle's sound system. It also doesn't matter what player I use or if I add any equalizer settings to the audio. Finally, the noise is present whether the car is running or not.
Can you guys confirm: If you pause the audio on your player does the whine end about 4 seconds after and startup again if you press play? Or if you shut the player down does the noise go away shortly after?
I did some research and some said it has to do with the AUDIO DAC in the phone turning on and off as audio is played, paused, etc. If the output device has high sensitivity these sounds appear.
I had another issue with my Plantronics wired headset distoring when making phone calls. It did not present the whine but it distorted the callers voice as if the treble or bass was too high. I tried various audio settings but nothing changed. With other headsets the issue does not present itself. I think that the audio DAC is also sending higher/lower frequencies that are greater than some headsets can handle.
That Kensington thing that was posted can easily be made with common household parts. Basically all you need to do is take the big bulgy thing from any cable that would have it and attach it to your audio cable. It works best if you have one near each end of the cable. it's called a clamp-on ferrite bead and is just a clip with iron ferrite in the middle. Since i'm new I can't post a link buuuut what I can do is tell you the keywords to look up on google for the ehow link: cable magnets eliminate emi . enjoy!

I am getting this with headphones, i have used multiple brands and its hit or miss but more hit than miss :laugh:, anyone getting it in there headphone?
I was getting this issue until I installed a custom ROM. Running MeanROM right now with no background noise. Seems counterintuitive to me...but whatever.

Dankorzon, is this what you're talking about? If so I'm going to go get some tomorrow. I'm having this feedback issue too, but it is only when the car charger is plugged in. But I'd love to get rid of that sound. Drives me crazy.
SOLVED: I used a ground loop isolator
I posted earlier that I had the whining noise in my car even with the engine off. So it wasn't related to an alternator issue. I use a Blitzsafe (blitzsafe.com) device to add a line level input jack to my Honda Accord's stock radio interface. It works well with all my other devices except the Evo 4g LTE. This past weekend I did a little tinkering and noticed that if I pulled the RCA jack on one channel (left or right) every so slightly so the ground tabs weren't touching the noise disappeared. With only one channel connected the noise is not present. I'm not sure why the noise is present with both channels connected but it definitely pointed to a ground loop problem. I did some research in audio forums and some said that a wire could be jumpered so the RCA ground touches the receiver chassis and that would solve the problem. Unfortunately that did not do anything. I touched several different grounding points near the receiver but the sound was always present.
I went to Best Buy and purchased this: http://www.bestbuy.com/site/Fierce+...36.p?id=1218186610567&skuId=9855136&st=ground loop&cp=1&lp=1 It works great. For whatever reason the EVO 4g LTE's DAC must be sensitive or not have the right filter to block the ground signal. This explains why the Kensington product also works.
I also solved my headset issue. I can confirm that older corded Plantronic headsets will not work well with the EVO. The EVO distorts the speaker in the headset. I'm pretty sure it's because it sends lower bass frequencies than the speaker can handle. Only solution was to use a newer headset.
Thanks all for your help.

That is what he is talking about, but that is NOT what the kennsington device is. Google "ground loop isolator" for info on what the kennsington is, it is NOT simply an aux cord with ferrite beads on it.
I've got the same problem in my car. This only happens when plugged into the charger. I'm going to try a ground loop isolation device which will arrive sometime next week.
I guess I don't understand why the phone would only do this when no music is playing though. It makes me think maybe a patch could solve the issue if HTC knew what the issue was.

I was on my nightly bicycle ride using Cardio Trainer and my Skull Candy Smokin Buds, and everytime id move the phone in my bicycle jersey near the headphone jack it would cause the music to skip/stop/ff sometimes try to voice search and sometimes try to redial out ... I can replicate the problem here at home by jiggling the headphone jack around abit .......... anyone else
Yes. I posted the exact same thing in Q&A forum. Got no response but I figured it out.
Sometimes when you plug in your headphones they are detected as a headset. It doesn't occur that often, just make sure the notification icon doesn't have the microphone part. Otherwise any shaking causes songs to skip, phone to freak out and voice dialer starts.
Apparently there's also an app that makes sure they always do connect in headset mode. I think I'll go replace my phone anyway.

I had the same thing happen yesterday. I was testing some speakers at a job site and the phone was going CRAZY. I pulled the phone out of the otterbox case and re-plugged the headphone in and it was fine. I think my problem was the case + cable was not making the correct contact. Today I had the headphones from a PSP plugged in (with case) and it was fine.
Looks like its the same thing that was heading to my evo4g. The headphone input is design for 3 ring conductor (for remote control) but your headphone jack has 2 ring conductor thus making your phone act weird. I brought an adopter (you can go search amazon) and it fixed the problem.
go to marketplace and download "headset blocker". it wont show up in your apps list. go to 1 of your homescreens, and add its widget. its a toggle that you turn on and off. when its on, none of the headphone control features will work, and it it should just play your music without skipping tracks and what not.
I have the same issue did you ever figure it out?
Like previously mentioned this is because it is designed for a 3 ring conductor. 1 is left, 2 is right, 3 is microphone/control. The controls are back track, forward track, pause/play/answer/hangup. If you have a pair of headphones with 2 conductor (which is fine and it is also designed for) you are good. If, however, you aren't making full contact (because of cases being in the way or you have a 'non standard' headphones, read: cheap ****) wacky things can happy from intermittent contact of the various points.
I've never experienced this on either phone, but, it is a thing and it makes perfect sense.
There is another possibility...that the jack is fncked up. Poorly soldered, defective jack, abused (all it takes it one good jerk on the cable to ruin everything).
It's not as random and wacky of a situation as it sounds like.
I have two different 2 ring (stereo) headphone cables from two different manufacturers and the cable has nothing to do with the issue in my case. The issue is not with headphone/earbuds and not with the cable not plugging in all the way. The issue for me is that when you have the headphone cable plugged into the jack and the other end is feeding any type of amp: stereo equipment, Aux input in a car, whatever, the phone absolutely loses its mind. I've tested it on three different phones now and it does it every time. The phone is unusable until you download, install, and activate Headset Blocker from the market. Then everything works perfectly. It appears to be a defect in either the hardware or the software because it is picking up electrical noise as headset control signals.
BTW, I've measured the cables and tested to be sure they plug in all the way. They are standard 2 ring (which means three conductor) cables that should not be triggering any headset functionality. Something on these phones is falsely triggering the headset connection: maybe some very small electrical signal or voltage coming from aux inputs because as I said, earbuds/headphones with the exact same connector don't have the problem.

I had the same problem and just swapped it for a new phone. If you're still under 30 days just take it back.

It sounds likely that it could be a grounding issue, probably on the amp side...though it could be on the phone side, especially if this happens to some phones and not others. If this is pro gear there is probably a ground lift switch on the back...give that a shot, if it doesn't help then it is definitely the phone...which I am leaning towards since it seems to happen on some and not others.
Headset Blocker from Market. I had a video on youtube about this and my thread is here.
i am having the same problem. thanks for the heads up for the headset blocker app. beats using up warranty or paying deductible for now.
I know this thread is 2 years old, but I figured bumping is better than starting a new thread. Anways, this issue has been driving me crazy to no end. Headset blocker stops the false signals. However, if it's in your pocket and the base of the jack is bent, (at least on Skullcandy products + HTC Inspire), music stops playing from the left ear.
Anyways, I figured out a solution to this. Cut a 3.4mm hole in a credit card, and then insert your headphone jack. Trim the card around where you insert the headphone jack. To get the right size hole, I use a knife to penetrate the card, and then use a screwdriver to widen the hole until it's about right. It should stop all interference and false signals, audio cutting when your phone is in your pocket and the headphone base is bent.
This also works on heaphones that have microphones; however, you have to remove the plastic piece if you want to use the mic.
Abaout those adapters on Amazon that someone mentioned; what do I search to find them?

Nope, it's certainly on the phone side.
I've had the same issues plugging it into my car and into professional audio equipment.
Headset blocker is great. I just keep it on all the time.
It was pretty funny sitting in the car and realizing that it's dialing everyone on your contact list though. Couldn't make it stop even after unplugging it. It went crazy.

i have the exact same thing on my device, but it happens with any headphones i have plugged in
moving them just a bit causes google now to launch repeatedly and the music to skip,play,pause,etc
to fix it i remember using a blocker from the market and editing the code that launches google now via headphones so the blocker would block it aswell
I plugged my headphones in for the first time today and i realized that the left side was quieter than the right. And I unplugged it and replugged it in and it was fine. Then I tried it again and the left side was lower again. I'm not sure what's causing this or if my tablet is defective. But it seems like a hit or miss on getting even volume from both sides.
Anyone else having this problem or can test it out?
I have te same issue and it happens every time I plug in headphones and its annoying.
For me this only happened when I use my SGS2 headphones on Nook.
Actually, I found that SGS2 headphones only work well on the SGS2. With my laptop they have tons of noise, on nook sometimes I have uneven volume.
Although on SGS2 they have the best sound I've ever heard in headphones..
Have you guys tried other headphones?
I only have the one pair of head phones and they are a generic brand from dollar general and they dont have any issues when i use them with either my pc or psp or phone for that matter

No issues here.
Headphone bug
Yes I too have that problem. Glad to see that it's not just me & mine.
Stupid question - for those having issues, have you tried wiggling or rotating the plug once it is plugged in? Sometimes I find if I have a spot of oxidization on the plug it will cause said uneven volume. It could explain the difference that occurs when you unplug/plug back in.
Another thing to try would be to plug them in when the device is asleep to see if that helps. If there is anything that tries to reduce the "pop" of the sound of plugging in the headphones it *might* affect how they sound after the fact.
Just grasping at straws here based on my experience with other devices.
I was having this problem until I realized I only had my headphones plugged in half way. Don't mean to be a jerk, but have you tried plugging your headphones in just a little further?
Sent from my DROID BIONIC using Tapatalk
no amount of fiddling with the plug helped me at all still have the issue and its annoying since the speaker isnt loud enough when I am out and about.
Another thing to consider - another issue I've had with certain device/headphone combos is that some headphone jacks either don't have a long enough plug or the plastic jacket of the jack interferes just enough with the plug in the device to affect sound (essentially related to downsay's comment). Try a cheap pair of 'phones from the dollar store with a simple jack and see if the problem persists. If so, perhaps the device is defective...
These are a cheap pair of head phones from dollar general lol.
Edit: Plugging the headphones in while the device was asleep seems to have fixed the issue for me for now. Sound is equal in both cans now
I have tried 4 different earphones, they have been plugged in all the way. Some people have no problem, so I'm beginning to think this is a hardware defect. I'm going to exchange mine and will let you guys know if there is a difference. I'll also try out the display model and see if it suffers from this problem.
Glad to hear you got them to work. Please do let us know how it goes with returning the nook tablet.
Sent from my DROID BIONIC using Tapatalk
I replaced my Nook twice partially due to this issue. Same problem on all three and it's always the left channel that is not connecting properly. I have found that I can get a good connection by plugging the jack in slowly. I think this is more a software issue than a hardware issue.
Yea just exchanged my tablet as well and the same issue is there as well as the one at the store. Plugging in slowly does help. Just before it engages the last click, if you hear both channels you're golden. Hopefully this is a software issue because it seems to be random. Unfortunately the one I exchanged has a creaking case, so now back to exchange again.
I stopped by Radio Shack this afternoon and purchased a $5 female to male 1/4" stereo connector. It seems to have solved the problem. I had similar problem years back with an iPaq PocketPC. Due to the shape of the hole on the iPaq/Nook, the headphone/earphone connector isn't inserting deeply enough.
Another solution would be to use something like a Dremel Mototool and shave away some of the excess material on the headphone/earphone adapter, so it can insert a little bit deeper.

What is everyone testing their audio on? The stock media player? Video (what program)? Is it on every application you try?
I haven't had any issues with audio in games, websites or MX player at all other than a loudish pop when some programs start up, but I'm using a set of Denon stereo headphones (so, good (large/long, gold) headphone plugs on it, jiggling the connection does nothing).
Hello everybody i recently got the sprint car dock and i was wondering if anyone else has seen this same kind of behavior as I have been seeing. Basically music played using the 3.35mm jack to an aux port on the car stereo just doesn't sound right. It seems like all the sound is going to my rear speakers while i play music from RDIO and my streamed music from Google play. It seems like the audio sounds much better while the phone is not docked. Has anyone else run into this issue? I remember that original Evo's dock did something where it automatically lowered the volume of the music being sent through the 3.35 jack.
When I had the photon and the dock, I had the same issue. Do you have a case on your phone?
If you do try to push down a bit harder with music playing, I bet you your other speakers will start working again.
The USB audio is picky on just how "properly" seated it is. I also noticed (again the photon) the audio is a bit quieter. Eventually I ended up using the mini jack connector and the usb for charging.
So after re-reading your post, I realized you are not talking about USB but the mini jack. What i have noticed however, I was using the 3.55mm today and the radio had to be turned up a bit more to get the normal listening levels I am currently used to (used to be 22-24, now its 30-35 for volume level on my radio) The sound did sound a bit.... off... but could not quite place it. I noticed the beats audio icon on the top when I had the music playing. It does not appear to be customizable except for an on and off?
anoying sound
As soon as I inserted my phone into the car dock with my 3.5 audio jack in it started making a buzzing sound. I double checked that the phone was seated properly and that the audio jacks were all the way secure. The sound disappeared as soon as I removed it from the dock. It is not very noticible if music is playing but if is not it is terrible. Am I the only one?
This is likely a ground loop issue. I'm seeing it with my dock too. But i also see the exact same issue while charging WITHOUT the dock and always have with every phone in my truck. Unplug the charger, issue goes away.
Eventually I'm going to re-ground my cigarette outlet to a cleaner ground in my truck and see if that solves the issue.

Id have to agree. I dont have the sound issue in my truck atm, using an aftermarket Pyle 7in dvd. But Ive had that same issue in other vehicles/devices (not with my LTE). Does the sound increase with the RPM at any range? If so they make a filter (I think its just a magnet idk) that can clear up that sound.

I do not have the issue at all when I disconnect from the dock. In fact, its minimal once I start to play something like Pandora. But as soon as I don't have something playing the buzzing kicks in and its annoying as hell. I have two 12v ports in my car and several different chargers and it does them for all of them. I think it may be something HTC knows about but hasn't confirmed yet...

I'm not saying that it wasn't the case for you, because it certainly is possible. However, correct me if I am wrong, you had the problem regardless of if the phone was in the car dock correct?
I ONLY have the problem when it is in the car dock. That makes me think it's not the 12v plug.

Can you try something? Take the same charger and try it with the phone in another car. One thats less then 10 years old if possible. (Not that its some magic age of the car, just better/properly grounded radios are more common, imo) Report back and let us know if the sound persists in that vehicle? Thanks
*Not saying yours, or anyone with the problems vehicle is 10+ years old - just wondering if it persists elsewhere.

I've had it on multiple devices that had their power adapter plugged into the car. There is also a chance it's your power adapter.
This is not an uncommon problem in car audio, it's so common that many manufacturers make devices to try to reduce the noise. http://www.radioshack.com/product/index.jsp?productId=2062214
Try adding a ground loop isolator into the audio cable. They can't be bought just about anywhere (Amazon, Radio Shack, etc.) for about $15 and should eliminate and ground loop noise. Ground loop noise is why it is so hard to find a car dock that includes audio out. Companies understand consumers want a car dock with 3.5mm audio out but wouldn't be able to design a dock that would eliminate noise in every case.
Filtering the audio line with a ground loop isolator is not a solution for me. They often dramatically reduce high tones and degrade audio quality overall. A real solution is to solve the issue on the electrical side, not the audio side.
OK, I think I understand what you are saying now. I get the normal ground loop whine that I have always gotten in my truck, that changes pitch with RPMs. Known issue with all phones in my truck, whatever.
But today I also noticed a Static (1 second) Static (1 second) Static (1 second) Static (1 second) that was only noticable when my phone was in the dock, plugged in, no music playing (in between songs) AND the beats audio logo was visible (beats was off, I do not use it). Beats logo goes away (when there is more than a second or two of silence) and the static stops. I'm not sure if the static is stopping then because the beats signal processor is turning off, or because the phone is turning off power to the headphone jack. If it is the beats processor turning off, I could try to make a mod to always keep it off (I don't use it anyway).
Is anyone seeing this static (static, not whine) while plugged in but NOT in the dock?
Is this what the OP is seeing? How about the rest of you?

OK, I think I understand what you are saying now. I get the normal ground loop whine that I have always gotten in my truck, that changes pitch with RPMs. Known issue with all phones in my truck, whatever.
But today I also noticed a Static (1 second) Static (1 second) Static (1 second) Static (1 second) that was only noticable when my phone was in the dock, plugged in, no music playing (in between songs) AND the beats audio logo was visible (beats was off, I do not use it). Beats logo goes away (when there is more than a second or two of silence) and the static stops. I'm not sure if the static is stopping then because the beats signal processor is turning off, or because the phone is turning off power to the headphone jack. If it is the beats processor turning off, I could try to make a mod to always keep it off (I don't use it anyway).

I am not the OP but I am getting the exact same results that you are. It sounds perfect when not in the dock. When in the dock it makes a terrible buzzing noise until I start to play something. I have tried multiple chargers including OEM HTC ones in multiple vehicles and the problem still persists. How can ground loop be non existent when I'm charging my phone with just the cable (outside of the dock)? It has to be something else. I ordered the HTC Stereoclip yesterday and should have it be the end of this week to test wireless play.

I already had one installed for my Epic, and still get the noise on my EVO....
Just out of interest, is the 3.5mm jack going into the Phone, or is it tied into the charger cable. I currently have a MOTO Atrix and the Car Dock USB Cable splits off with an Aux Jack connection. That way you don't need to keep plugging the Aux Cable into the phone everytime you dock. I've never had any interference with this approach.
I'm getting the EVOLTE as soon as possible, so I'm interested in this answer. Plus, how it's being connected may be part of the problem?

There is no audio jack coming out of the dock. You still have to use the one on the phone itself.
So I took apart the dock and there is one small chip inside. Seems like a lot for what should just be usb passthrough. I tried removing the blue led hoping that that was the cause of the interference but it did not help.
There are lots of resistors and capacitors on this board. Does anyone know of we remove them all it will be straight usb passthrough? I get MUCH less interference in my truck with just charging and NOT the dock using the same cable. I good way to test this is to turn the Media volume all the way down on your phone and up high in ur vehicle and you will get tons of static and popping.
Any electrical engineers in the crowd? I if not I guess I have to buy a stereo clip :-(

Activating car mode is done my simply shorting pins 4 and 5 on the USB connector, no electronics required and is why the dock will still put your phone into car mode when not even plugged in.
I've got an aux input in my car, and today when I tried plugging in my GSIII, I got met with a faint but annoying whistling sound underneath my music.
It stops if there's no sound being sent over the wire, but the moment a notification (or music) starts playing, it comes up.
Car worked fine with my DX, and still works fine with my friends' iPhones, but I get the stupid sound with my brand new galaxy siii. Oddly enough, it works fine with headphones.
any ideas guys? I'm kinda stumped.
Search ground loop isolation. You are getting dirty power to your phone.

Do you have the phone charging through the cigarette lighter? You can get ground noise from there, and it will be transmitted through the phone to your stereo.
Hm. Let me try again without it charging, but that's strange. Why did my old DX not experience this?
Assuming that's the issue - will a different cable solve the problem?
edit: So I checked the phone without plugging it into the charger. Still get a whistling noise. It's really more like a high pitched hum. I notice that if I don't plug the plug in all the way it doesn't happen (but I think I only get one channel).
I'm getting the same thing, and it's driving me crazy. At first I thought my brakes were going bad in my car!
I've tried different audio players and apps, but it still always get the noise. The phone is not charging, and I did not get this with my old captivate either.
Any ideas?
Doesnt happen in my Porsche. I'm using Bluetooth audio though.

I am having the same issue. First time experiencing it though; never heard it with the iPhone, HOX, or NS
I'm using a line in cable, and when i jiggle it, i can hear the noise change tone at the same time. I have a feeling it might be because it's a regular stereo cable and the microphone combo jack on the phone is not working right with it. But that's just a guess.
It's pretty annoying and its making the phone unusable as a music player.
Happens in my Lamborghini (Dodge Caravan) when using a MP3 player. Usually, if I run my hand down the cable it clears as though it's some kind of static build up in the cable.

try flipping the cable (putting the aux in side into the phone and the phone side in the aux in) it happens to me sometimes and if I flip the cable it clears it out I couldn't tell you why though. also make sure there isn't any dust in the ports or on the cable ends.
That noise you hear is most likely due to the electrical system in the car. I rent cars all the time for work and never know the shape the electrical sys is in so to resolve the issue I bought a Kensington Cable from amazon and now have CD quality sound from any music app including pandora & spotify.
Hope this helps.:cyclops:

Unfortunately, my cable is RCA on one side (L+R channels split) and regular 3.5mm on other.

Not sure what you mean by "the electrical system" and the "shape" of it. Could you clarify? As I said, I have no problems with other devices in this car.
I would usually suspect something wrong with the car, or maybe a ground loop, but I can plug in my Galaxy S (Captivate) or iPod with the same cable, same everything, just switching out the phone, and the noise goes away.
The way the noise cuts in and out between songs, and when I close the music app, it seems to only happen when the audio chip is getting a signal or is being energized. This is making me think that it may just be a noisy chip :crying:
I was on conf call with SGS3 plugged to AUX, no power charging was going on. And either noise canceling didn't work, or noise was getting in thru AUX line to receiving end. I didn't have problems listening, but ppl on the other end complained, and I had to mute the mic.

sorry! Could you speak up please? I couldn"t hear you over the sound of your e-penis
I am having the same problem. My HTC Thunderbolt never had this problem. Same car and cables, I get the hissing and popping until I play something. Then it goes away until I stop the music and then it comes back again. Weird and disappointing.
The problem comes from the 4-pin (TRRS) audio jack in the GSIII combined with presumably bad grounding in my 2007 Honda Accord, or the Aux adapter.
I fixed it with a simple DIY solution. I cannibalized a TRRS headphone jack and bought a TRS (3-pin) port from radioshack. I clipped off the jack with a generous portion of wire, then stripped them and cleaned them from their insulation (they are covered in insulating dye).
I connected 3 of the wires to the TRS connector, and taped the whole thing up. No more hum.
Also known as Road Noise. Where the power cable and audio input are too close to each other. Electrical current emits a small magnetic field which will hinder audio quality and promote road noise from the alternator.
This is a very typical senario in car audio install, when you run the power cable and rca right next to each other.
this buzzing noise happens to me every time i drive my car for the past 3 years:
solution: turn down the car volume. if you keep your car volume half-way, then you wont hear it as much, or you wont hear it at all.... you can make the phone volume as loud as you want though. also, as you accelerate faster, the noise gets louder. watch, try it.
So figured I'd go ahead and add a thread about this here for us Sprint users that are experiencing the problem with the Aux cable. Its a known issue and I'd link to a couple other posts, but I'm still a "noob"
I was a little upset to find that I wasn't able to use my phone to Pandora in the car.
However....
Today I got it to work, and here is how: I had the stereo set to the CD player when i plugged the AUX cable in and the icon stayed in the notification bar. Then I launched Pandora and let it start playing. THEN I switched the stereo to AUX mode, and it played fine my entire trip to work. Still experienced the "hot plug" sound between tracks, but I think I can deal with it.

I recall having an issue with my samsung headphones. They didn't work at one point, I rebooted and they were fine. The phone didn't even detect them for some reason. I've had no issues with aux in my car (aside from needing a new cable), however I thought it would be worth mentioning that my Note 2 had an issue with aux when it is on any AOSP ROMs. Selecting any app, even swiping the notification window down, sometimes even just leaving the music app and going back will stop the music from playing. The only solution for this was to go to the home screen unplug the aux start music playing and plug the cable back in and touch no other app. Again, it never did this with stock. I even went back to stock briefly because of this. AOSP seems to throw a fit with the aux cables.
I had issues with AUX today as well. Thought it was my specific phone but I'm relieved to know it's common....and perhaps a software issue.

Yeah I have it as well...I've found if I start Spotify, then plug in the AUX cord from my car, it works fine.
So I think I know the answer to this one.
It seems to have to do with how cars and some other devices treat aux inputs. For the most part it appears (at least in the case of my Prius) that with the input switched to aux the phone would not consistantly stay aux mode. What it seems like was happening is that the car doesnt actually 'activate' the aux port unless it senses a completed circuit (ie: audio playing). I have to believe this has to do with preventing feedback.
Unfortunately it seems the phone does the exact same thing. The headphone or aux symbol appears on insert of the cable because the phone senses the initial connection but then finds no load on the circuit thus assuming it is not connected and disables the port. You end up with basically an electronic stalemate. Neither one engaging cause they sense nothing from the other side. No load on the circuit.
Bear in mind this is completely dependent on the device you are connecting to your phone, as to whether it does what I'm talking about. Likewise, those experiencing popping or similar during song or track changes would basically be experiencing the same issue as during the song change the phone stops playing audio and your car kills the port. When the car kills the port, the phone kills the port, or is in the process of it when the next song starts.
To counteract this I bought an audio cable with a ground loop circuit built in. It is designed to remove the buzz from car aux audio due to the phone or other device being charged through the car's power system. But the added benefit is that it creates an artificial load on the line that the phone senses. Same idea as plugging in headphones as the earphone on the headphones creates a load on the line in the same way.
This is the audio cable I bought. Works like a charm every time, although one warning. I did experience one case of very loud static when unplugging it through the speakers in my car because of the fact that the car and the phone believe the circuit constantly is active and thus do not kill the connection to save your hearing. So be careful to only plug or unplug it when the input is not active or the car is off.

It does appear that Amazon has put the item under review for now, though I'm not sure why as mine works flawlessly, but any similar car aux noise reducing cable would work, assuming its decent quality.
An aux cable with an in-line volume control should peform similarly due to the load created by the potentiometer, although it wouldnt remove the charger buzz.

I just want my G3 to work as it should for such a simple function as the headphone jack/aux port.
I want to listen to music in my car without fannying around with different cables etc etc.
I had a Galaxy Note and S4, both played fine in the same car with the same cabling.
Shame on LG for releasing us a substandard product that cannot perform the most basic of tasks correctly.
I will say, i was extremely dissapointed when i plugged my shinny new phone into my stereo and the audio continued to come through the phone speakers. All other phones/devices work just fine in my car and there is no reason why my G3 shouldn't either.

My first feeling was confusion. I was also worried my headphones wouldn't work. But I was able to watch a beautiful high def video on my phone last night with my headphones on
Sent from my LGLS990
I just got this phone too, and although I love it, I was very sad to have this issue! I haven't had it on any other phone I have owned, so I certainly hope it is fixed in a future update. That and the video force close bug, but that is for another thread!
Guys, there is nothing wrong with the AUX port on your cars -- and they don't trigger via sound. They trigger via either conductive circuitry or via ohm load. Can you test if you are still seeing these problems when *not* charging? This issue is typically related to bad grounds. This happens to me at work when my phone is charging and I plug my headphones directly into my G3. If I pass the audio to my PC first (to the line-in,) and THEN to my headphones, the static is mostly gone.
So try unplugging the power source, and using different aux cables. Another factor is try plugging the power source into the same feed as the stereo. Sometimes this isn't that easy though.
What's happening on the back end with the sound changing between songs, etc, is that the audio codec, (the chipset,) is turning off to conserve battery. For me, when the chip turns on, it grounds the 3.5mm port just fine, and when it's off, AND I have power connected with headphones, I can get that whine -- depending on the scenario. So basically, this is by design -- an energy conservation tactic. I would be okay with them leaving the audio chip on the entire time headphones are connected.
Had this problem too and found that as long as I was charging the phone it would play like it should.
Yep, grounding issue. At work, routing the aux signal through my PC works just fine WHILE charging -- if I unplug, then I get all the machine noise.
In general, though, the headphone output is pretty crappy on this device. Even when it's "working great," there is still a faint amount of white noise that can be heard. Much higher than my HTC M7. The S5 had similar performance as the G3 though.
I just bought:

And plugged it into:
http://www.amazon.com/gp/product/B00F474DVG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
So when I get in my car, it connects to the dongle for music and the car's blue tooth for phone.
It's not perfect, but gets the job done.

Still have the "computer talk" garbage noise related to the display coming through the left channel.

aux problem
I guess I lucked out with my phone but then again maybe not. First off I will describe my setup, I have a 05 Subaru WRX with stock 6cd changer head unit ( no aux port ) I installed a Harmon Kardon Drive + Play iPod dock. This allows me to remote control my iPod and comes with a display that shows tracks and such. It works by FM transmitter but has an optional wire which I have that connects directly between the antenna and the stereo so you get little to no loss of signal. Between the AUX and my phone I connected a PAC SNI-1/3.5 3.5-mm Ground Loop Noise device. My previous phone was an LG Optimus G which I loved, when I hooked this phone up I could listen to Pandora/TuneinRadio through my car speakers and upon making/receiving a call I would hear the call through the car speakers and when I talked the phone mic. would pick up my voice. When I attempt this with the G3 I get no popping between tracks but the phone mutes the mic and when I say mute I don't mean the mute button comes on I mean the other person can't hear me. I found if I unplug and plug the phone in during the call eventually the mic works again, but to do this while driving defeats the purpose of hands free calling. Does anyone else have this problem? (or a solution).

Bumping this thread because I just started having issues. Last night I was listen to music with headphones and my device kept turning itself down. I thought it was Tasker at first but it kept happening. Today at work I wanted to listen to music on headphones again and the sound would only come through my device. I'm going to try an aux and other headphones when I get off work, but does anyone know if a system restore will fix this? I'm rooted with TWRP, I just don't want to wipe it for nothing.
